To all whom, t may concern:

Be it known that I, Mn'r'rnnxs Cnnis'r- MAN, a citizen of the UnitedStates, residing at Springfield, in the county of Greene'and y State ofMissouri, have linvented certain new and useful Improvements. in Hub-Plates for Vheels, of which the following is a specification, referencebeing had therein to the accompanying drawing. A

This invention relates to hub plates yand theA principal object of the.saine is toV provide a hub plate which lW'ill permit lubricant to passfrom one side of the hub plate to the other so that the amount offriction will be reduced to the minimum.

This invention is illustrated in the accompanying drawings, whereinzr# YFigure 1 is a perspective Viewk of theimproved huh plate. Fig. 2. is a.perspective view of one of the sections of the hub plate.` Fig.A 3 is aView of one of the liners which l surround the hub plate and hold thelsections together. Fig. 4 is aview otone of the liners which ispositioned within the hub plate and which assists in holding thesections together. Fig. 5 is a fragu'ientary View of the hub of theWheel showing the improved hub plate in place. transverse sectional Viewalong the line 6-,-6 in Fig. Fig. 7 isl a transverseectional View alongthe line 7- 7 in Fig. 5. Y

This hub plate is intended to beused on the driving wheels, truck Wheelsand trailer Wheels of a locomotive and is seatedwithin an. annularrecess 1, which is formed in the inner face of the' Wheel 2 and isspaced from. the central opening 3l of the .Wheelby an annular shoulder4. This shoulder is reduced so that itis slightly sunk beneath thesurface of the inner face of the Wheel hub.

The hub plate comprises a pair of sections 5 andG each of which is.semi-circular. Y The lpla-tes of the sections are held together bymeans of the tenons 7 which are formed upon the ends of the section 5and fit vWithin the Inortises 8 which are cut in the ends of 'thesection 6. The inner portion of each of the sections is reduced and iswith the internal groove 9 andy with the eX- ternal groove 10. B vhaving the inner portion of the section reduced the ledges l1 and 12 areformed, upon which the locking liners rest. v

f Grrease `is supplied 1 to-the groove117 by means of a grease cup whichismou'n'ted in the hub'of the wheel'.` Thegreasecupis threadedexternally landinternally and is which is y'formed in the hub of the.WheeliandWh-ich 4l-iasfasre'-v threaded into a socketQG duced extension27 leadingtoa'therecess 1 and positioned so 'as' to communicate 'Withthe groove 17. A force plug 28 is threaded into the grease cup 25 andgives a pressure to the grease so that the grease will be given a higherpressure, and, thus, i to be better' lubricated. t

In the operationof-this device 4,thea-plate is inserted in the recess 1and' is held therein by thelinerbands 15. The Wheel is placed upon theaxle 29 and :the'hnbwplate rests against the bearing box 30. Grease ispoured into the grease cup and vt-he plug 28 is threaded into place sothat the grease is forced into vthe groove I17 and through the causethe'Wheel all times.

-sure by the plug dowei :pins 21 4to the grooves 19 and the` lng. underhigh pressure lso that the space between the different parts of thewheel and' hub plate are completely filled with oil at It should also benoted that `the dowel pins hold the hub plate against inde- 4 pendentrotation so that there is no danger of the wheel turning without the plate being also turned. It should also be noted 'that the ends of theplate sections are provided With the grooves so that grease can passfrom the groove 17 to the spaces between the inner faces of the linerbands and plate so as to assist in holding the liner bands against thehub.

What I claim is 1. A wheel provided with an annular recess in one face,a hub plate seated Within said recess, said plate in saidv recess andfor permitting the passage of lubricating material through said plate.

2. A Wheel provided with an annular recess having sockets formed in itsinner end, means for -admitting grease to'said recess, a hub. platemounted within said recess and provided With. openings formedtherethrough and registering with 4said sockets, and pins passingthroughsaid openings in said plate andintosaid sockets to hold saidplate in place and being also provided with openings to permit alubricant to pass through .said plate.

cess, a hub plate mounted within cantlthrough said hu vided -with anannular 'communicating with said 3.; A Wheel provided with an annularresaid recess, the inner face of said hub plate being progroove, saidplate being provided with a plurality of openings, the outer face ofsaid plate being provided with a plurality of pockets and with groovesconnecting'said pockets with said openings, and a grease cup positionedWithin said Wheel and communicating with said annular grooves formed insaid plate.

4. A wheel provided with an' annular recess, a hub plate. mounted insaid recess, a lubricant holder mounted in said Wheel and annularrecess, the passage of a lubriplate, the outer'face of said hubV platebeing provided with pockets and .with rooves leading to said pockets,

and means or retaining said hub plate within said recess.

5. A wheel provided with an annular re-y means for-permittin -with 'aplurality of o enin and common means for securing e' "and means forholding said hub plate in a hub and for l passage of'lubrica nosas??`cess and with a plurality ofsockets formed` 1n the inner end of saidrecess, ahub plate positioned within said recess and provided 'reistering with said sockets, and ho low owepins passing through saidopenings in said plateand into said sockets tohold said plate inposition, and to form conduits to of a'lubricant throu h said' plate.

'6. A wheel provi ed with an annular recess, a hub plate mounted withinsaid recess,y

said hub plate formed oa plurality of sections, means for locking saidsections together, and'common means for preventing the'rotation of saidplate Within said recess ,and for permitting the. passage of a lubricantthrough said plate.

7. A hub plate, and means passing through said hub plate for securingsaid hub plate in a hub to prevent independent rotation of said hub andplate and for permitting the passage of lubricant through said hubplate.

8. A hub plate provided with openings, passing' through said openingspermitting the passage of lubricating material through saidl plate. 1

v9. A hub plate provided with openings, and securing pins for preventingindepend- .ent rotation of saidhuband plate passing through saidopenings and provided with longitudinally extending openings to permitthe passage of lubricating material through said hub plate.

l0. A hub plate provided with openings, one face of said hub plate beingprovided with recesses, and with grooves connecting said recesses withsaid openings, and securing pins passing through said openings andprovided with openings adapted to permit the passage of lubricatingmaterial through said hub plate.

1.1.-A hub plate formed from a plurality of sections, means for holdingsaid sections together, and means for holding said hub plate in positionand for permitting the ting materialthrolgh' said hub plate.
